Relative Coastal Vulnerability for Channel Islands National Park. The colored shoreline represents the relative coastal vulnerability index (CVI) determined from the six variables.  The very high vulnerability shoreline is located along sandy stretches of coast where regional coastal slope vulnerability is high and significant wave heights are highest. The low vulnerability shoreline is located along rock cliffs where coastal slope is steep and wave heights are low.

The Coastal Vulnerability Index (CVI) provides insight into the relative potential of coastal change due to future sea-level rise. The maps and data presented here can be viewed in at least two ways: 1) as an indication of where physical changes are most likely to occur as sea-level rises; and 2) as a planning tool for Channel Islands National Park.
